For non-standard networking setup (like the one where you have eth0:1)
it'd be much easier if you let the OS handle the bridge and have
something like (network-script /bin/true) on xend.sxp. So for example
you can have these files

/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-xenbr0
/etc/sysconfig/network-scripts/ifcfg-xenbr0:1

which would create the bridge xenbr0 with eth0 as physical device and
create a virtual interface on xenbr0:1 where you can assign a second
IP address.

An advantage of such approach is that you don't have to depend on xend
for network setup. You can restart xend anytime you want and
networking would still be OK.

Let me know if you need more detail on this setup (like what those
file's contents look like).
